It all apparently depends on what the meaning of "not yet" is.
CBS affiliate KLBK in Lubbock reports that Terrell Owens has signed with Dallas and will be introduced at a press conference on Monday.
The Ranch Report refutes the claim, but in the most tepid fashion, saying,
"according to two sources close to Owens, he has not yet signed a contract of any kind with the Dallas Cowboys."
That's oh, non-emphatic, shall we say?
